Comment # 4 on bug 92722 from 
I have attached a sample Xorg configuration for using the radeon driver,
basically the Ubuntu fglrx configuration (fglrx works on Ubuntu 15.10) with
"fglrx" replaced by "radeon".

The radeon driver basically seems unable to find a screen to its liking, 
> (EE) RADEON(0): No modes.
> (EE) Screen(s) found, but none have a usable configuration.
and then gives up altogether:-
> (EE) no screens found(EE)

This happens irrespective of whether the module parameter radeon.runpm = 0 or
not. Trying to use vga_switcheroo with echo DDIS >
/sys/kernel/debug/vgaswitcheroo/switch results in a reversion to the login
screen with a message saying that client 0 refused to switch, or in a totally
black screen (but the system keeps working and can be powered off normally by
pressing the power button), after logging out, depending on the display manager
being used (the former typically happens with GDM).
